Thank you so much - I'm currently undergoing treatment with one of these very machines, have a science background, and I'm the kind of patient who feels much better when they understand what's going on. This really helped me.
Me too... I don't think the technicians in the room know who clever the machine is... I guess the folk in the back-ground on the PC have a good knowledge...
@@flyduck1 he is a lecturer in computer science in Wales and as of 2023 is still posting answers to questions on Quora, so I'd say that's a successful treatment!
This is such a great video! The explanation is simple and precise. I had 38 daily treatments with this machine. 5 years out and still cancer free. The technology is amazing.
I'm a cancer patient visiting this machine every day. I barely notice any side effects, I have another 1/2 month to go, 10 minutes a day. This machine is amazing!
The animation or whatever you call it is amazing, the animation really help with understanding how the machine works, if I only would of heard the lady speak I would be completely lost, amazing animation guys, awesome.
Thank you so much for providing this information. As a family physician, I understand the basic principles of radiation therapy for cancer, but was really clueless as to what my radiation oncologist did when 'planning' my treatment and how the machine actually worked.
i imagine this is expensive but nonetheless, the care it must have taken to make each marvellous engineering decision must have been laborious. I can't believe the amount of care one must have to have such precise measurements and such a high level of safety. It makes me happy to know that there are people who dedicate their lives to making these life-saving machines
This is an excellent presentation. If you are being treated with a Varian linear accelerator there are a few small differences (klystron vs magnetron, placement of focus and steering coils & other components, type of bending magnets) but the principles are all the same. Bravo Elekta!
I am a cancer patient and this machine has been used daily on my tumour and the site of the lymph nodes in the arm pit. I am grateful for this video presentation.
@@russellhamner4898 Yes, I'm now 7 years out on one cancer and 6 years out on another, so I'm still here and doing great! Thanks for asking! A tip of the hat to the folks at Johns Hopkins in Baltimore and a myriad of other doctors spread around DC & MD. A big thanks to them!
Each person undergoing Radiotherapy,really needs to watch this important presentation, Without these wonderful machines, and the people behind them,many would be clutching at straws to get help. Thank You
I have 34 years of hands-on experience working with high vacuum systems, high powered radio frequency generators (including magnetrons), scanning electron microscopes, ion implanters (industrial particle beam accelerators used for doping semiconductors) and, industrial real time microfocus X-ray systems. I'd really enjoy working with this piece of equipment because it appears to be very well-designed and because it is used to help people in need.
Explain is fantastic and easily understand even not in a medical educated viewer like me i am in india at tamilnadu state ,my father age 63 affected in throat cancer grade 3 and lungs also damaged by TB and having more fibrotic tissues in lungs (because tb patient and long time smoker) so doctor prescribed RT/CH and they are say anything will happen while on treatment even dead so I need your suggestions for linac RT and my family is very poor family but our government started yesterday linac treatment in chennai with free so I need your suggestions please please please.....
Thank you - this is very clear. I'm a current patient of radiation therapy, and it really helps me to understand how the technology works. This is a big help, thanks!
Very well explained! The animation further helped to visualise and understand the concept. I really liked the addition of magnets near the end of the waveguide to further pinpoint the electrons on the target which is also unique with elekta.
Excellent animated presentation. I have been keen to know how this machine works as it rotates around during my therapy visits. The variable focusing system is really smart.
What an excellent video. This answered pretty much every question (and I had a lot) I had about the machine and also the process being used to treat me for prostate cancer. Every radiation oncologist should know about this video for the education of any curious person like me with a lot of questions.
I am also undergoing treatment. UNC Rex has a few of these Electa machines. They’re so cool, I had to find out how they work. This was extremely helpful.

Wow! This video is very interesting. Recently, I study about LINAC. And I watch this video about its application. Thank you for providing this information.
I know I'm going to get some hate for this. But essentially it looks like it's a highly advanced CRT (like an old school TV) that has a cavity magnetron (like you find in a magnetron from a a microwave) pumping RF into it. But instead of phosphors at the end its tungsten (like in a enhanced radiation nuke)
Very interesting, the animation is really well done. Was looking for an electromagnetic explanation of a Linac, found an awesome inspiring video on medical engineering, still worth though! Thanks a lot!

Nice presentation. I was wondering, to bend the electron beam you would normally use a dipole and not a quadrupole? Is that something to do with off-axis acceleration? I am assuming that the magnets near the delivery point are dipole/septum magnets. Also, are you by any chance looking into ion/proton therapy? Thanks
Does anything here remind you of the train in the Nation of Wakanda? If "yes", you are observant. This presentation is very accurate and very easy to understand for a lay person. As a certified Radiation Therapy Technologist,, and an Engineer, I strongly recommend.
The Society for Applied Microwave Electronics Engineering & Research (SAMEER) MEiTY exchanged MoU on Magnetic resonance imaging (MRI) and technology transfer of Linear Accelerator with industry. About Linear Accelerator or LINAC It’s the device used for external beam radiation treatments for patients with cancer. It uses microwave technology to accelerate electrons which collide with a heavy metal target to produce high-energy x-rays. Then the high-energy x-rays are directed to the patient's tumor to destroy cancer cells
Thanks for this wonderful video... I'm currently recieving radiation treatment and as someone else said in the comments I feel much better knowing how this thing works. Also just curiosity as I have an engineering background. Amimation is superb and the narrator is great with her clear voice.
and let me be clear. All the above apply to radiotherapy with photons (X-rays and γ-rays). When it comes to radiotherapy with hadrons (protons, neutrons, heavy ions or even pions) the process differs a little bit.
1st of all gamma radiation consists of high energy photons. It's true that healthy cells are more sensitive to radiation than cancerous cells. But they have very different recovery rates. That means that if these different types of cells take a sublethal radiation dose the healthy cell will recover faster than the cancerous cell. That's why we do radiation therapy in sessions.
Brilliant animation. The dedication of the scientists and engineers is not acknowledged enough. Technology beyond the understanding of most, if not nearly all of us. My wife was trying to tell me what happened when she received the treatment - now I know. All on the NHS - no charge. What would you be paying in USA I wonder.
Hello! Can someone explain to me what would happen if this specific machine has a general failure in the LINAC, also in the backup center, and they find lost IP directions?
